09f5e97 ("travis-ci: skip a branch build if equal tag is present",
2017-09-17) introduced the "skip_branch_tip_with_tag" function with

Hi,

previous discussion:

Sorry that this trivial fix took so long.

Cheers,

Thanks for the fix.

09f5e97 appears to be for the ls/travis-scriptify branch, which is
already part of "next" (if it weren't, I'd suggest just squashing your
patch into that commit).

Git style is to use 'test' instead of '[' for this.  See
https://public-inbox.org/git/2f3cdc85-f051-c0ae-b9db-fd13cac78aed@gmail.com/
for more on that subject.

Could you squash in the following?

Thanks,
Jonathan

Oh, you're right!

@Junio: Can you squash it when you apply the patch?

Thank you,

I do not mind and I already did.

The patches in the series this patch is fixing up were solely about
splitting these scripts out of the YAML file as-is, and I think it
was correct to carry these style differences over without adjusting
them.

But resulting scripts in ci/ are riddled with styleguide deviations,
which may want to be cleaned up later.  There also are some
bash-isms marked with "#!env bash" in them, but I think they are OK
because we know we are running them only at a very specific place
and the need to make them portable is very small.

Thanks.
